STOVE OR RANGE.

SPECIFICATION forming part of lLetters Patent No. 449,918, dated April'7, 18.91. i

Application filed March l0l 1890. Serial No. 343|289. (No model.

To all whom t may concern:

Be it known that I, CLARENCE V. ROBERTS, a citizen of the United States,and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Stoves' or Ranges, of which the following is aspecification.

My invention relates to that class of stoves or ranges in which a boileris located at the back of the range and above the top plate of the same,one of theobjects of my invention being to so construct a stove or rangeof this character as to provide for the snug fitting of the sameintoaspacebutlittlc, if any, wider than'the rangeitself, a further objectbeing to provide simple and effective means for causing thev circulationof water between the water-back and the elevated boiler or reservoir.These objects I attain in the manner hereinafter set forth, referencebeing had to the accompanying drawings, in which Figure l is aperspective view of a stove or range of the class to which my inventionrelates, illustrating` one of the features of my invention. Fig. 2 is asectional view, on a larger scale, illustrating the construction of thewaterback and circulating-pipes. Fig. 3 isa transverse section of thewater-back. Fig. 4c 1s a sectional plan view of the same; and Fig. 5 isa sectional view of part of one of the boiler-supporting brackets, withpart of the boiler shown in elevation.

In Fig. 1, A represents the body of the range, and B a boiler orwater-heater mounted upon end brackets D I),so as to be supportedhorizontally some distance above the top plate of the range. This boileris connected by means of circulating-pipes with the waterback in thefire-box of the range, and, as usually constructed, theseconnecting-pipes are at the end of the'range structure and are providedwith elbows whereby they are connected to the end of the boiler and theend of I nd, however, that these end connections are not essential tothe proper working of the device, but that, on the contrary,circulating-pipes extending from the bottom of the boiler to the top ofthe Waterback serve the purpose quite as effectually, and by the use ofpipes of the latter character I am enabled to locate them inside of thesupporting-brackets for theboiler, instead of outside of the same, asusual, so that the range will :fit into a space of considerablylesswidth than a range of the usual construction, this being an import-antfeature of advantage, as ranges of this character are largely used insmall houses, where the spaces between doors or between the chimney-breasts andthe walls, door-frames, or partitions are generallylimited. The supporting-brackets for the ends of the boiler are alsodished or recessed for the reception of the rows of rivets which securethe heads of the boiler, as shown in Fig. 5, so that no portion of theboiler need project beyond said brackets.

Although different arrangements of circuletting-pipes may be used incarrying out my invent-ion, I prefer those shown in Fig. 2, in which Frepresents the casing of a rectangular water-back having within the samea transverse partition a, forming an inverted funnel G.

From the bottom of the elevated boiler B to the top of the outer casingof the waterback extends a pipe Il, and within this pipe is a secondpipe I, which extends from the top of the funnel G to a point in theboiler B above the bottom of the same. The cool water in the bottom ofthe boiler therefore descends through the outer pipe II and around thefunnel Gr to the bottom of the water-back, and on being heated ascendsthrough the said funnel and pipe I into the upper portion of the boiler,constant circulation between the boiler and the water-back being thusmaintained. Another advantage of this construction, moreover, is thatbut two water-tight joints have to be formed-wiz ,those between the pipeII and the top of the water-back casing F and between said pipe and thebottom of the boiler. A central coupling J on the pipe II may, however,be used in some cases to facilitate the setting of the parts. Thepartition a is preferablyinclined inward from the front or fire-box sideof the water-back casing to the rear of the same, as shown in Figs. 3and 4, so that the greater portion of the descending body of water willbe at the rear of the water-back and will not be heated by contact withthe front of the casing until it enters the funnel G, orsuch inclinationmay only be at the top of the partition, if desired.

IOO

Having thus described my invention, l claim and desire to see-nre byLetters Patentl. The combination of a stove or range, the elevatedboiler and the supporting-brackets therefor, a Water-back having apartition dividing it into two communicating' chambers, andcirculating-pipes extending from the top of the Water-back to the boilerand located on the inside of the supporting-brackets, one of said pipescommunicating with one charnber of the Water-back and the other pipecommunicating with the other chamber of the same, substantially asspecified.

2. The combination of the elevated boiler, 15 the water-back casing,`having a transverselyinclined partition forming an internal funnel insaid water-back, a pipe connecting the boiler and water-back casing, andan internal pipe extending,` from the funnel up into the boiler,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribingr Witnesses.

CLARENCE V. ROBERTS.
